MOLD FOR CONCRETE CONSTRUCTIONS.

Specification of Letters Patent.

Patented Mar. 14, 1911.

Application filed July 9, 1909. Serial No. 506,748.

T o all whom 'it may concern:

Be it known that I, IIENRY C. SEIPP, a resident of Coraopolis, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Molds for Concrete Constructions; and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a mold for concrete constructions and has special reference to the formation of what are commonly known as pavement or sidewalk lights, floors, roofs, vaults, walls and other parts of buildings.

The object of my invention is to provide for a cheap, simple and eiiicient means for forming such constructions, whichy will enf able them to be formed rapidly, cheaply and conveniently, and will allow for the easy and rapid placing and removal of the forming parts and for their use at other places.

My invention consists, generally stated, in the novel arrangement, construction and combination of parts, as hereinafter more specifically set forth and described and par ticularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains to construct and use my improved mold for concrete constructions, I will describe the same, refer ring to the accompanying drawings, in which- Figure 1 is a plan view of my improved mold for concrete constructions, partly broken away, and showing the same applied to form a sidewalk light. Fig. 2 is a sectional view on the line 2-2 Fig. 1. Fig. 3 is a like view on the line 3 3 Fig. 1. Figs. 4, 5 and 6 are plan, side and end views, respectively, of the metallic mold section. Figs. 7 and 8 are plan and side views, respectively, of the spacer plate. Figs. 9 and 10 are side and edge views, respectively, of the reinforcing bar. Fig. 11 is a sectional view of the concrete construction mold, showing the same applied to form a roof. Figs. 12, 13 and 14 are sectional views of other forms of the reinforcing bar. Fig. 15 is a sectional view of the concrete construction mold, showing the same applied to form a wall.

Like symbols of reference herein indicate like parts in each of the figures of the drawin s.

gAs illustrated in the drawings, in the formation of sidewalk or pavement lights and across varying widths of areas.

my improved mold for concrete constructions is built up, as shown in Figs. 1, 2 and 3, by first placing the temporary ledges 1 on the ordinary standards or trestles 2, and such ledges are so arranged that they will conform strict-ly to the profile of the sidewalk or street. These ledges 1 support a metallic mold 3 formed of series of sections, such as is shown in Figs. 4, 5 and 6, which are laid upon said ledges side by side and parallel to each other to form such mold, and such sections when in position to form such mold serve at once as a pattern, a support for the glass or other tile, a support for the reinforcing bars, and as a uniform spacer for the tiles, as hereinafter described.

Each of the sections for the mold 3 is preferably made of cast metal, such as iron, and is provided with a body portion 5 having the mold cavity 6 therein of grooved or trough-shaped form. The walls 7 of the grooved mold caidty 6 are parallel to each other horizontally, and the space or distance across the same diminishes toward the bottom of the same and increases toward the top thereof to form a tapered mold cavity. At one or both ends of the grooved body portion 5 on each section for the mold 3 and extending out at right angles therefrom are the flanges 8, which are provided with bolt holes 9 therein, and when these sections are placed upon the ledges 1 as before described, bolts 9 connect the sections together through such holes and form such mold of any length desired to reach from the said lelcges rojecting from the flanges 8 are the flanges 10, which extend parallel with the groo-ved body portion 5 and are provided with the bolt holes 11 for the bolts 12 to connect the parallel sections .of the molds together, if desired, through the iianges 10 on said sections, while such flanges 10 also act as a uniform separator or spacer for said parallel sections.

The parts of the sections of the molds 3 which abut against each other are machined true and straight, as well as the top faces of the grooved body portion 5 and flanges 8 and 10 on such sections to insure flush and finished joints or connections, and even and regular surfaces in the finished work.

When the sections of the molds 3 are thus placed in position on the ledges 1 and connected together by the bolts 9 and 12, a reinforcing bar 13 is placed in the grooved cavity 6 of the body portion 5, and such bar er um ew V. r-, u is formed of a flat piece of metal-S1Je4lkfasl8rts troweled and Worked down to 2L Steel, which has ierrbeclyr@miem 51,0%@ iin-deed.eurieegild @V811 with Such vided with openings l5 through the same op surfaces of the lenses or tiles.

osare? ment and combination of my improved concrete construction, as well as changes in the shape or design of the structure formed thereby, may be resorted to, without departing from the spirit of the invention, or sacrificing any of its advantages.

It will be evident that my improved mold for concrete constructions will enable the work of building structures to be performed in such a manner as to permit the use of a supporting means to act as a mold or former for such work, and such means can be used continuously in this work and for different kinds of structures, while such construction can be applied in forming various structures other than those described, and will permit the employment of different forms of glasses, lenses or tiles, or supporting or reinforcing bars. The structures formed by the construction will be strong and durable, will be light in weight and material, and will present to the eye a neat and finished piece of work.

That I claim as my invention and desire to secure by Letters Patent, is-

l. In a mold for forming side-walks and other like constructions, the combination with the supporting means, and a series of parallel removable mold sections of troughshaped form on said means and adapted to support lenses or tiles placed between the same, said sections having abutting flanges and L-shaped side flanges for connecting the ends of the mold sections together and the parallel sections.

2. In a mold for forming side-walks and other like constructions, the combination with the supporting means, and a series of parallel and removable mold sect-ions of trough-shape form on said means and adapted to support lenses or tiles placed between the same by the trough walls, said sections having abutting flanges and L-shaped side flanges for connecting the ends of the mold sections together and the parallel sections.

3. In a mold vfor forming side-walks and other like constructions, the combination with the supporting means, a series of parallel removable mold sections of troughshape form on said means and adapted to support lenses or tiles placed between the same by the trough walls, and means between said lenses or tiles and supported on the said walls for spacing said lenses or tiles.

4. In a mold for forming side-walks and other like constructions, the combination with the supporting means, a series of parallel removable mold sections of troughshape form on said means and adapted to support lenses or tiles placed between the same by the trough walls, and metallic plates between the lenses or tiles and supported on said walls for spacing the lenses or tiles.

5. In a mold for forming side-walks and other like constructions, the combination with the supporting means, a series of parallel removable mold sections of trough-shape form on said means and adapted to support lenses or tiles placed between the same by the trough walls, and metallic plates between and Linder the lenses or tiles and supported by said walls. y

6. In a mold for forming side-walks and other like constructions, the combination with the supporting means, a series of parallel removable' mold sections of troughshape form on said means and adapted to support lenses or tiles placed between the saine by the trough walls, and metallic plates between and under the lenses or tiles to space the saine, said plates having cutaway corners for fitting around the lenses or tiles and having its endsbent up for engaging with 'said' walls to support the same.

7. As a new article of manufacture, a sheet metal spacer for lense or tiles in pavement lights and other like construction having its ends extended upwardly for engaging with parallel supporting means for the lenses or tiles.

8. As a new article of manufacture, a sheet met-al spacer for lenses or tiles in pavement lights and other like constructions having its corners cut away and its ends eX- tended upwardly for engaging with parallel supporting means for the lenses or tiles.

In testimony whereof, I, the said HENRY C. SEIPP, have hereunto set my hand.
